Since 1981
Mau West is one of the leading and fastest growing waterproofing firms in East Africa. We are total experts in new and old gutters, roofs, water retaining and water excluding structures.
If you look at our portfolio, we have repaired a lot of swimming pools in the past. From below ground swimming pools to suspended swimming pools. But what makes waterproofing an art is that every swimming pool we have repaired has had different approaches job. This is because site conditions and requirements vary from project to project. This is the reason why I always advocate for waterproofing professionals for each project
In this case, we handled a very interesting swimming pool because of the history it had. The pool had been previously repaired 4 times but it was still leaking. 4 times!!!. So when the owners called us for help, they were really drawing their last straw.
Problems and Challenges
Notice the leakage coming from the slab
Removing terrazzo, plaster and screed

The Solution
Together with the Structural Engineer, the contractor and our team, we decided to double waterproof the pool. This meant using to materials to waterproof the pool, namely Penetron Admix, Penecrete mortar and Duraflex cementitious membrane. And on top of that we decided to cast a new concrete slab (with Penetron Admix) on top of the existing one.
We decided to take this cautious approach because no historical data was present. In such situations, I always take the approach of worst case scenario.
The following were the steps taken:
Casting the concrete slab. The concrete was mixed with penetron admix
Vibrating the poured concrete
Casted concrete slab
Applying Duraflex cementitious membrane
Duraflex is a ready to use flexible slurry based on a special synthetic resin dispersion and a blend of selected cements mixed with carefully graded aggregate
Duraflex is used for :
-Protection and repair of balconies, terraces and haunching concrete of roads and bridges.
-Waterproofing of new and old buildings (internal and external)
-Waterproofing of tanks, containers and water reservoirs.
Duraflex application on a plastered surface
Duraflex can be applied by a brush or a roller
We used Ecofelt reinforcement mesh

The pool was tested and it was watertight. Next, tiles were laid and the pool was ready for use
