atal Contracting Ltd

Atal Contracting services has developed organically from clients using our specification and supply services.

Atal Contracting Limited are specialist structural waterproofing contractors.

Our clients were demanding that we use our expertise to carry out the installation of below ground waterproofing systems on which we aided the design, giving not just peace of mind but also a 10-year installation warranty, extendable by premium to 25 years with an option of independent insurance backing.

What we do

We offer a complete installation service from design through to completion for both new buildings and to existing structures, including maintenance services where required. Our installation service complies with recommendations set out in BS 8102:2009 Code of practice for protection of below ground structures against water from the ground.

Our technicians are also proficient in leak detection and repair.

Our specialist installers are supported by CSSW trained technicians who are able to provide waterproofing designs based on site-specific requirements to meet BS-EN 8102:2009, NHBC Chapter 5.4, Premier and LABC waterproofing requirements.

All of our installers carry relevant and up to date CSCS cards, are fully trained on the application of external membranes, internal cavity drain systems, podium deck waterproofing and ground gas protection and are supported by CSSW qualified technicians.

Our structural waterproofing installers then carry out waterproofing works on site following the details and datasheets to provide our 10-year warranty, extendable by premium to 25 years with an option of independent insurance backing.

All of our installers are trained and experienced in the installation of our specialist materials.

External Tanking

We are skilled installers of numerous Type A waterproofing systems including self-adhesive membranes, cementitious coatings, multi-coat renders and sodium bentonite membranes. We find the installation of atal Bentofix to be the most cost-effective type A system. Our installers are experienced in the installation of Bentofix, which can be installed in all weather conditions. This reduces delays and additional labour costs.

Internal Tanking

Our installers are experienced in the installation of internal tanking, either Type A or Type C. Atal Type C internal cavity drain installations can be used as a second line of waterproofing defence on a new building or primary remedial waterproofing of existing structure. Due to stresses placed on existing structures by installing Type A internally, we usually specify a Type C system. Water within the internal cavity drain system would be gravity fed to an outlet on a semi basement project and discharged using a sump with pump on a full basement.


We offer a range of hand applied, third-party accredited coatings including elastomeric cementitious, elastomeric polyurethane and epoxy coatings. Application includes both internal and external tanking to both new and existing substrates, for use on both vertical and deck application. Our coatings are UV stable, rapid curing and easy to install.

Concrete Repair 

Atal has a team of experienced surveyors in concrete repair who attend site and provide full reports with recommendations to remediate any problems. We have a full range of materials for repair and resin injection systems.

Leak Repairs

Our CSSW registered surveyors attend site and provide a full report with recommendations to remediate water ingress problems. We have a full range of products for all solutions.

Sumps & Pumps

Our qualified CSSW surveyors can advise on sumps and pumps for all groundwater conditions and can design accordingly.

Atal are installers of structural waterproofing and ground gas protection materials. All of our installers are trained and experienced in the installation of our specialist materials.

Our specialist installers are supported by CSSW trained technicians who can provide waterproofing designs based on site-specific requirements to meet British Standards, including NHBC, Premier and LABC waterproofing requirements.

After work has been completed, we provide a ten year Atal Contracting Limited installation warranty with an option for an insurance backed guarantee.


The customers that have been supplied with the admixture have been pleased and we have had no issues with strength or quality.

The change to the bags sizes(introduction of the water soluable bag) has made it easier especially for manually handling on the plant side.

The atal service has been fantastic, the architect specified the types of waterproofing that we’d need. We had early design meetings with atal and the main contractor and from that point we’ve gone through the whole process from design to copmletion. They’ve been great.
