Pervious Concrete is a special type of concrete that has a high porosity so that water can percolate through it easily. The major advantage of this type of concrete is that it can be used in the areas where it is very important to remove the stagnant and there is no proper draining facility for removal of water.

The pervious concrete is made only by implementation of course aggregates and cement for binding the aggregates. The fine aggregates are not used so that the pores between the course aggregates are not blocked. This pore serves as a gateway for the water to percolate through the concrete substrate.

Pervious concrete is used in parking area, subways and residential streets and walkways. The pervious concrete s used in a wide range for stromwater management. It is one of the sustainable product and concrete of future generation.

History Pervious concrete was first used in the 1800s in Europe as pavement surfacing and load bearing walls. It can also reduce city temperatures and alleviate urban hot island phenomena. Pervious concrete was first invented in Britain in 1824. It was first introduced into the United States in the mid-1970s and has since been rapidly developed. The Sponge City was introduced in China in approximately 2012.

Need of Pervious Concrete A large amount of rain water ends up falling on impervious surfaces such as parking lots, drive ways, sidewalks rather than soaking into soil. This creates an imbalance to the natural ecosystem and leads to the host of problems such as erosion, flood, and groundwater level depletion and pollution of rivers. The best solution to avoid this is to alter the impervious construction surface such as concrete and asphalt by the pervious concrete. Pervious concrete also acts as a filter which removes the debris from the flood to enter into the rivers and ground water and recharge the water level.

Properties of Pervious Concrete It has just enough cement paste to bind the aggregate with each other. The aggregates that are used should be only course aggregate and fine aggregate is avoided.

Fresh Concrete Property: The plastic pervious concrete mixture is stiff compared to traditional concrete. The slump that is measured is 30 mm which is enough for placing the concrete.
However, slump of pervious concrete has no correlation with its workability it is not be specified as an acceptance criterion.

Hardened Concrete Property:
The density of the concrete is found to be 1800 kg/M3.
The void contents of the pervious concrete ranges from 20 to 25%.
Typical flow rates for water through pervious concrete are 120 L/m²/min.

Speciality Concrete Admixture – Polycarboxylate Ether

Chemical admixtures are usually added as liquids or powders in relatively small quantities and may be used to modify the properties during the plastic or hardened state of concrete. Chemical admixtures can be divided into five types: accelerating, retarding, water reducing/plasticizing, air-entraining, and waterproofers. One such chemical admixture specially developed is the Modified carboxylic ether admixture. It offers much larger flexibility in molecular design. Polycarboxylate ethers (PCE) contain groups with polyoxyalkylene, especially polyethylene or polypropylene glycol groups as well as carboxylic acid and/or carboxylic acid anhydride monomers. Fairmate is also manufacturing this product. Fairmate’s Brocrete SCC is a specially formulated admixture based on modified carboxylic ether. It produces flowing concrete that can consolidate under its own weight. It is supplied as a yellowish or whitish colored liquid, miscible with water. It is specifically designed to flow easily through highly congested, heavily reinforced areas.

• Seals micro-channels in concrete against water penetration and chemical attack.
• Hardens – making concrete stronger and abrasion resistant.
• Dust proofs-creating a cleaner, healthier environment.
• Permanent – One penetrating application.
• Easy maintenance. Makes cleaning easier. Reduces staining.
• Satin sheen to concrete.

Recommended Uses

FAIRCRETE 17 is used for surface hardening of new and old concrete to prevent dust generation and to reduce wear, particularly on exposed concrete. Typical areas of application include warehouses, factories, platforms, car parks, corridors etc., on both new and existing concrete surfaces.

Application Instructions

Surface Preparation:
The substrate shall be thoroughly cleaned of all foreign materials such as bond breakers, curing agents, form release oils, dust, construction laitance by light mechanical grinding if required. Clean the surface with a high pH detergent and wash thoroughly. The surface shall be saturated with water and later excess water has to be removed.


A low pressure, high volume sprayer shall be used to apply FAIRCRETE 17 so as to form a glistening sheen and to ensure complete saturation of the surface. Enough FAIRCRETE 17 shall be applied to keep the surface wet for at least 20 minutes.

If applying by hand, spread the sprayed material with a lambs wool roller once or twice and then stop spreading. If spread excessively, it tends to dry in streaks. After 20 minutes, the excess material shall be removed and the surface shall be allowed to dry for 1 – 2 hrs. The floor is ready to use after the surface is dry. A light lithium residue may form on the surface after the floor is dry. This is the excess FAIRCRETE 17 liquid floor hardener which was not absorbed and can be removed by a stiff broom or power sweeper. For an immediate shine, FAIRCRETE 17 shall be allowed to dry overnight and then polished with a high speed buffer equipped with a black pad, followed by a red pad.

Sealing / Overcoating / Striping:

The treated surface can also be painted for striping as there will be no chemical incompatibility between FAIRCRETE 17 treated surface and these paints.


Floors treated with FAIRCRETE 17 benefits from good routine maintenance. Regular scrubbing with a high pH detergent is recommended and can increase the shine. Tyre marks can be removed with a citrus type of cleaner. Oils and acids should be removed properly to prevent damage.

Packing and Coverage

Packing : FAIRCRETE 17 is supplied in 20 & 200 ltr containers.
Coverage : Spray applied – 10 – 12m² per Ltr on power trowelled surfaces. On textured surfaces the coverage will be much lower.



Water leakage and seepage is the enemy of all structures. It is important to build correctly with due attention to water proofing of basements, exterior walls, roofs and building watertight pipelines. Large numbers of structures lack proper implementation and thereby have less life. If water enters and starts damaging any part of the structure, early repair action must be taken. For excessive damaged structure restoration may be possible by use of repair chemicals after ensuring structural safety.
We realize there is a need to provide building professionals with suitable specialized information to enable them to ensure higher life of all structures. FAIRMATE CHEMICALS PVT. LTD. is a step in that direction. In the developed countries, use of Construction Chemicals is quite extensive. India has to catch up with high growth rates in this field.
Leakage is a common problem in any home or structure, caused either by the age of the structure, or improper
construction and design methods. Some of the most common reasons for water leakage in structures are elaborated below:

1.Construction Practices

• Untrained man power
• Improper preparation of mortar and concrete mixes
• Use of excess water for to make mixes easily workable, which results in porous concrete, inviting leakage.
• Bleeding & segregation in concrete resulting in honey combing/voids
• Inappropriate compaction/vibration of concrete
• Inadequate curing in early and later stages
• Negligence in site supervision.

2.Inappropriate Material Selection

Enough care is not taken in specifying the correct construction materials such as :

• Right quality & grade of cement depending on service requirements
• Good quality crushed aggregates of various sizes depending on mix proportion
• Sand free from silt and other chemicals
• Potable water, i.e. water should not contain any chlorides, etc.
• Other chemical and mineral additives that can increase the durability of construction

3.Aggressive Climatic Conditions

Environment plays an important role in determining the durability of any structure. More aggressive the climate, more stringent is the precautions to be taken. Structures which are exposed to marine regions or situated in polluting industrial belts, are more prone to chemical attack.

4.Mechanical Damage

Concrete structures are not often used only for the purpose they have been designed, but subjected to forces such as excessive loading, impact, abrasion and other mechanical damages. As a result, structural cracks develop in slabs. These too contribute to the problem.

5.Inadequate Maintenance

Problems like cracks, dampness, etc. are neglected in the initial stages and timely corrective measures are not undertaken, ultimately leading to deterioration of the structure. It is advisable to undertake preventive maintenance and carry out timely repairs through a competent contractor, the correct specification for materials and methods, depending upon the problem.

Diagnosing the root cause of the problem is vital. Only then a suitable solution can be arrived.
The treatment will then be cost effective from the long term point of view. Repair or maintenance must be done

systematically as under:
Visual inspection

Non destructive testing as advised by a consultant or an expert, if required Once the diagnosis is done, a proper scheme can be made to undertake repair and rehabilitation work using suitable materials aided by construction chemicals.
