WET AREA WATERPROOFING

These are areas where water is continuously used for utility purpose or bathing. Wet areas are always critical location for seepage. There may be several weak spots such as wall joints, faulty piping that corrode are often the point of leakage. The moisture spreads through the floor and walls causing extensive damage. With development of new construction technologies and depending on space availability.

WATER RETAINING BODIES

Water retaining bodies includes swimming pools, ponds, reservoirs, potable tanks, sumps, overhead tanks, STP, Dams etc. These structures are filled with water and are constantly under pressure depending on the depth of the structure also are in contact with different types of chemicals hence have higher chances of leakage. It is necessary that the waterproofing system can handle these factors.

TERRACE WATERPROOFING

Roof/Terrace Area-Waterproofing of any terrace area in general is very complex as it is exposed to variable weather conditions, foot traffic etc. It is often the leakage through the terrace that causes severe dampness in the ceilings, thus spoiling the look of expensive interiors and also leading to weakening of the roof slab and concrete

PODIUM & LANDSCAPE WATERPROOFING

Podiums form the base of any building/structure. It is subjected to a lot of stress such as being exposed to changing wreathing conditions, decorative features such a planters and heavy traffic. (Foot/ vehicle etc.)

HEAT REFLECTIVE COATINGS

Roof being one of the most affected parts of a building as it is directly impacted by heat, being exposed to extreme weathering during summer, it causes rise in temperature of the interiors of the room below, hence using such a system would help solve the problem.

EXTERNAL WATERPROOFING

External waterproofing can be classified into 2 major groups- External Crack Rectification and Expansion and Control or contraction Joint Treatment. It is very critical to take care of the exterior for any building as these forms the primary barrier to stop/ block water from its entry into any structure. Due to degrading construction quality, cracks and joints are a big concern. It needs to be treated with great care otherwise even a good waterproofing system can fail. By thumb rule, for any crack/gap the Width: Depth ratio is 2:1 and general coverage is 600 ml/120 RM/ mm (RM-Running meter)

INTERNAL WATERPROOFING

Internal Waterproofing this refers to the waterproofing of the internal walls that show efflorescence due to ingress of water by capillary action. It is generally observed that the walls along side of wet areas show efflorescence /damp patches of the paint. This rising dampness issue due to capillary movement of moisture can be concealed by treating it using selective products.
Recommended solution by Aquaseal Polymer based Elastomeric coating system– these systems are high performance elastomeric coating which a very tough and can withstand negative water pressure up to a certain degree only in case of rising dampness. They can be divided into 3 types-

1. Single Component Pure Acrylic
2. Two Component cementitious
3. Two Component Epoxy

REPAIR WORK

Concrete Repair -This involves patch work fixing of specific weak zones.

The different kind of weak zones are as follows-

Cold joints– Cold joints are formed primarily between two batches of concrete where the delivery and placement of the second batch has been delayed and the initial placed and compacted concrete has started to set. The full knitting together of the two batches of concrete under vibration to form a homogeneous mass is therefore not possible, unlike the compaction of two fresh workable batches of concrete. This could be a potential plane of weakness.

Construction Joints- are made where the concrete placement operations end for the day or where one structural element is cast against previously placed concrete. These joints allow some load to be transferred from one structural element to another through the use of keys or (for some slabs and pavement) dowels. Note that the construction joint extends entirely through the concrete element.

Honeycomb/voids– develop due to lack of proper compaction.

Cracks are a result of to improper mixing rations or lack of adequate curing resulting in entry of water.
Tie rod Holes– is a result of shuttering boards held together during concrete pour. These are very common spots of leaks.

Pin Holes- These are imperfection in the concrete surface caused due to excess air entering into the mix or improper de shuttering.
