Basement tanking
A continuous membrane barrier around the basement walls and slab that keeps groundwater out of the structure.

Below ground, water pushes in from every side. In coastal and high water table areas of the UAE, a basement needs a continuous waterproof barrier that is designed in from the start. We design and install below-ground waterproofing for towers, villas, malls and infrastructure.
Basement waterproofing
Since 1986, Western International has completed more than 2,500 projects across the UAE and Saudi Arabia.
A continuous membrane barrier around the basement walls and slab that keeps groundwater out of the structure.
For walls cast against piling or a neighbouring structure, where the outside face cannot be reached later. The membrane goes in first and the concrete is poured against it.
Injection solutions that seal cracks, stop leaks and stabilise existing structures.
Joints designed and treated to accommodate movement in the structure without letting water through.
Specialised products and methods that safeguard below-ground concrete from environmental and chemical damage.
EPDM, PVC and HDPE membranes for basements, protected by HDPE boards during backfilling.
Materials
We are proud to represent the world's best waterproofing manufacturers in the Middle East, and our site teams are trained in every aspect of the systems they install.
Questions
Tanking means wrapping the below-ground structure in a continuous waterproof membrane, under the slab and up the walls, so groundwater cannot get in.
It is used where a basement wall is cast against piling, shoring or a neighbouring building, so the outside of the wall can never be reached. The membrane is installed on the retaining side first, and the concrete is poured directly against it.
Often, yes. Injection systems can seal cracks and stop leaks in existing structures. Contact us with details of the problem and we will advise on the right approach.
Send us the drawings or describe the problem. One of our engineers will get back to you.
