Introduction

Water plays a crucial role throughout the construction process. From mixing concrete to controlling dust, proper water quality and filtration is essential for successful building outcomes. Poor water quality can lead to weakened structures, corrosion, health hazards and additional costs. This article will examine the science behind water’s importance in construction, the dangers of using unfiltered water, and the benefits of hiring the right tools to ensure access to clean, filtered water onsite. Discover how innovations in water filtration and tool hire services are improving sustainability, safety and quality in the construction industry.

The Science Behind Water and Construction

Water is one of the most important ingredients in construction. Here’s an overview of some of the key scientific reasons why:

• Water is essential for concrete, mortar and stucco – These materials are made by mixing water with cement, sand, and binding agents. Water facilitates the chemical reactions that cause the mix to harden and gain strength. The quality and quantity of water affects the properties of the final product.
• Water impacts strength and durability – Using the right amount of clean water results in properly hydrated cement and uniform mixing, creating strong, durable concrete. Too much water increases shrinkage and permeability while too little water results in uneven curing.
• Water affects viscosity and workability – The amount of water impacts the viscosity and workability of materials like concrete. More water makes concrete more fluid and easier to pour and shape. The ideal water content provides maximum workability without compromising strength.
• Water facilitates chemical reactions – Hydration reactions occur when water chemically reacts with cement to form calcium silicate hydrate and calcium hydroxide. These compounds crystallise and harden, binding the aggregate together in concrete.
• Water transports minerals and nutrients – Water dissolves ions like calcium, sodium and potassium and transports them through porous materials like concrete and wood. This facilitates structural changes over time.
• Water causes corrosion and deterioration– When water interacts with metal construction materials like steel, it can cause corrosion through oxidation reactions. Water also transports corrosive substances that damage materials.

Why Water Quality Matters in Construction

Using contaminated or unfiltered water can seriously undermine construction quality and durability. Here are some of the main water quality considerations:

• pH – Extremely acidic or alkaline water disrupts chemical reactions in cement and concrete. pH should be between 6-8 to avoid issues.
• Salinity – High salt content interferes with hydration and causes efflorescence and scaling. Salinity should be less than 3000 ppm.
• Hardness – Hard water containing high mineral levels like calcium and magnesium causes uneven curing and weaker concrete.
• Turbidity – Cloudy water with high sediment levels results in contaminated materials and altered strength/viscosity.
• Organic impurities – Organic contaminants like algae interfere with proper hydration in concrete and increase permeability.
• Inorganic impurities – Substances like chlorides and sulfates corrode steel and damage concrete when transported by water.
• Dissolved gases – Gases like carbon dioxide alter the water’s pH and reduces concrete strength if not addressed.
• Microorganisms – Bacteria and moulds can corrode materials and create health hazards if using contaminated water.

Proper water testing and filtration removes hazardous contaminants, creating water safe for construction use.

The Dangers of Poor Quality Water in Building Processes

Using unfiltered, contaminated water can seriously undermine construction in the following ways:

• Weaker concrete – Water with improper pH, salinity, hardness and impurities causes concrete to cure unevenly and have lower, more variable strength. This results in cracks and structural weaknesses.
• Corrosion – Impurities like chlorides and sulfates corrode steel reinforcing bars and other metal materials, causing expansive rust formation, leaks and reduced strength.
• Efflorescence – Salts and minerals leave white deposits on concrete surfaces as water evaporates. This results in an unattractive appearance.
• Permeability issues – Contaminants make concrete more porous and permeable to water. This causes leaks, facilitates freeze/thaw damage and undermines durability.
• Health hazards – Microorganisms in contaminated water can cause serious illnesses like Legionnaire’s disease. Workers are especially vulnerable.
• Formwork staining – Tannins, oils and similar organics stain formwork timbers, creating discolouration on finished concrete surfaces.
• Increased costs – Remediation work to address water quality issues drives up project costs. This includes tear-outs, structural reinforcements, mould removal and replacing corroded components.

Case Studies: When Unfiltered Water Goes Wrong

Here are two real-world examples of how using poor quality water created severe construction problems:

Rusting Rebars Force Concrete Repairs at Large Singapore Condo Complex

A luxury condominium project in Singapore had to repair over 2000 balcony slabs just 5 years after completion. The culprit? Corrosion of steel rebars caused by chloride contamination in the concrete mixing water. Removing and replacing the damaged slabs was estimated to cost around S$50 million.

Legionnaire’s Outbreak in Water System During Hospital Construction

Over 100 construction workers fell ill while building a hospital expansion in California. The cause was traced to Legionnaire’s disease originating in stagnant water collected onsite during construction and then dispersed in droplets through the ventilation system. Proper water filtration and testing may have prevented this.

These cases illustrate the potentially disastrous impacts of using poor water quality in construction. Proper water management is crucial.

The Hidden Costs of Ignoring Water Quality

While good water testing and filtration comes with upfront equipment and servicing costs, this pales in comparison to the expenses created by water quality issues:

• Structural repairs and replacements
• Increased maintenance and reduced lifespan
• Project delays and work stoppages
• Legal costs, fines, and liability damages
• Reputational harm for contractors and builders
• Risks to worker and occupant health & safety
• Higher insurance premiums

A recent US study found that over half of all construction warranty claims arose from moisture and water-related problems.

Clearly, ensuring access to clean, filtered water is a wise investment that saves money in the long run. The minimal costs involved are far less than the financial and reputational risks of ignoring water quality.

How Water Impacts the Durability of Construction

Using water of the right quality is crucial for constructing durable buildings and infrastructure. Here are three key ways water affects durability:

1. Permeability

• Clean water ensures properly cured concrete with low permeability.
• Contaminated water increases concrete porosity.
• Higher permeability allows more water ingress, raising freeze-thaw damage risk.

2. Corrosion

• Pure water minimises corrosion of steel rebars, metal components.
• Impurities like chlorides and sulfates dissolve in water and corrode metals.
• Corrosion destroys structural integrity and requires repair.

3. Carbonation

• Low-permeability concrete obtained with clean water resists carbonation.
• Carbon dioxide dissolves in pore water and reacts with concrete over time.
• Carbonation causes cracks, spalling and steel corrosion.

Water quality fundamentally impacts construction durability. Testing and filtration prevents strength loss, deterioration and structural failures over time.

The Role of Water in Different Construction Materials

While water is used universally in construction, its specific interactions vary across different materials:

Concrete

• Water hydrates cement and facilitates curing and hardening.
• The amount of water controls concrete strength, viscosity and workability.

Wood

• Water swells timber fibres, requiring moisture control to avoid warping.
• Water transports preservative chemicals like borates into timber.

Masonry

• Water combines with cement to bind masonry blocks and bricks.
• Excess water causes efflorescence on masonry surfaces.

Plastering

• Water hydrates plaster powder to create a workable paste for application.
• Water facilitates curing, improving plaster strength.

Steel

• Water corrodes and rusts steel over time. Coatings are used to prevent this.
• Water quenches hot steel, controlling its microstructure and properties.

In all materials, water quality control is vital for ideal outcomes.

Water and Concrete: A Crucial Relationship

Concrete is the most widely used construction material, and its quality is highly dependent on the water used:

Mixing Stage

• Water initiates cement hydration and lubricates the concrete mix.
• The water content determines concrete workability and pour characteristics.

Setting Stage

• Water continues cement hydration through chemical reactions.
• The water-cement ratio impacts the concrete’s strength and durability.

Hardened Stage

• Remaining water facilitates ongoing cement hydration and curing.
• Poor quality water leaves pores, reducing strength and increasing permeability.

Testing

• Water is added to concrete samples to assess strength development over time.
• Testing determines if water quality is compromising concrete properties.

Controlling water content and purity is essential across all stages of concrete production and use.

The Impact of Water on Wood in Construction

Water plays a key role in how wood performs in construction:

Moisture control – Wood swells and shrinks as it loses and gains moisture. Careful drying and moisture control prevents warping and instability.

Permeability – Water transports preservatives like borates into wood, but also carries damaging fungal spores and bacteria. Proper moisture levels inhibit microbes.

Rotting – Excess water promotes fungal and microbial growth, causing wood to rot from the inside out. Keeping wood dry prevents rot.

Adhesives – Water interferes with curing and bonding of wood glues. Low moisture content gives superior adhesive results.

Coatings – Water-based coatings hydrate and seal wood surfaces. Moisture control improves coating performance.

Fire resistance – Water slows combustion of wood and prevents cracking under fire conditions. But too much moisture causes steam explosions.

Controlling wood’s exposure to water through all stages of processing, treatment and construction is crucial for success.

Water and Metal: Understanding Corrosion

While vital for construction, water can also corrode and destroy metals through electrochemical reactions:

The Corrosion Process

1. Water dissociates into hydrogen (H+) and hydroxide (OH−) ions.
2. H+ ions from the water react with metal, causing oxidation.
3. Metal ions enter the water.
4. OH- and metal ions react, forming metal hydroxides.
5. Buildup of hydroxides destroys the metal over time.

Mitigating Corrosion

• Select materials with corrosion-resistant coatings.
• Use high-purity water to avoid contamination.
• Implement cathodic protection on submerged metals.
• Maintain alkaline concrete pH to passivate steel.
• Apply waterproofing coatings on metal surfaces.

Understanding water’s role allows corrosion prevention through careful material selection and water quality control.

The Importance of Water Filtration in Construction

Water filtration is essential for providing clean water for construction use. Here are key benefits:

• Removes particulates that weaken concrete mix integrity.
• Eliminates pathogens like Legionella bacteria.

Peace of mind – Rigorous water testing and filtration provides assurance that water-related risks are minimised during construction.

Water filtration is a low-cost, high-value intervention that prevents problems, reduces risks and improves outcomes.

The Science of Water Filtration

Water filtration leverages various physical, chemical and biological processes to remove impurities:

Physical

• Screening – Coarse filtration using meshes and screens to exclude large particles.
• Sedimentation – Particles settle out of suspension under gravity over time.
• Adsorption – Compounds stick to the surface of filtration media like activated carbon.

Chemical

• Ion exchange – Target ions in the water swap places with harmless ions bound to filtration media.
• Reverse osmosis – Water is forced through a semipermeable membrane to exclude dissolved contaminants.
• Disinfection – Chemicals like chlorine destroy microorganisms.

Biological

• Biofiltration – Microbes cultivated on filter media break down organic contaminants.
• Slow sand filtration – Microorganisms growing within the sand filter out pathogens.

Combining multiple techniques provides multifaceted water purification tailored to construction needs.

Different Types of Water Filtration Systems

There are various filtration system configurations suitable for construction water treatment:

Sediment Filters
