Christian Brothers chose MAU WEST CO. WATERPROOFING SOLUTIONS as the waterproofing contractor of choice for their leaking underground concrete water tank.
No company or individual in Nairobi, or even in Kenya, can afford to waste single drop of water. So when the institution of Christian Brothers discovered that their massive concrete water tank (over 5000 litres) could not hold water due to leakage problems inside the tank, they chose MAU WEST CO. WATERPROOFING SOLUTIONS to provide a permanent solution for the leaking water tank.
About the Client-CHRISTIAN BROTHERS
Christian Brothers is a congregation of Brothers in Kenya under the Catholic Church.
Their mission and work is to work is to make a difference to the lines of marginalized people through compassionate presence and seeking mutual transformation.
Cheap and poor quality waterproofing materials were the root cause of the leakage. Poor workmanship of the tank also contributed to the leakages of the tank.
George Massay, a fellow with the Christian Brothers, as frustrated by how the tank was losing water from the underground concrete tank. The waterproofing products that were used to waterproof the tank were not known, nor explained to the client how they work. Christian Brothers found their tank was having leaks which, apart from losing water, was leading to high water bills.
Christian Brothers were referred to us by reputable companies and when the opportunity came up to evaluate and inspect their water tank, we were more than happy to offer our expertise and solutions.
Mau West Co. Waterproofing Solutions inspected the tank and we found out that there was indeed a lot of work to be done. At the time of inspection, water from outside was leaking heavily inside the tank.
The construction joints on the wall were not waterproofed, as well as the construction joint between the wall and the floor slab. Both joints had visible signs of dampness, indicating that water was passing through the joints.
The floor slab was also poorly concreted. During hacking, we noticed several areas where the floor was weak.
How did Mau West Company’s solutions solve these challenges?
Considering the council water is rationed in South C, the client could not afford not to store water during the few days per week that water is available. Due to these challenges, the client’s decision came down to choosing MAU WEST CO. WATERPROOFING SOLUTIONS.
“We felt that Mau West Co Waterproofing Solution’s vast experience in waterproofing concrete structures gave us the confidence to trust them in solving our leakage issues.” Said Mr. George Massay.
All the honey combs present in the concrete wall were repaired using a combination of PENETRON & PENECRETE MORTAR. In areas where the honey combs were too severe, we laid concrete, instead of normal mortar. After that, we applied PENETRON INTEGGRAL CAPILLARY SYSTEM on the concrete wall.
The floor slab was also not well concreted. During hacking we discovered most areas of the floor were weak- therefore we decided to lay another concrete slab of 100mm thickness (class 30). We later treated the floor slab with PENETRON INTEGRAL CAPILLARY SYSTEM.
After treating the wall and the floor slab with PENETRON INEGRAL CAPPILARY SYSTEM, we laid and cured plaster and screed (ratio of 1:3).
|Penetron||A surface-applied, integral crystalline waterproofing material, PENETRON is used for waterproofing and chemical protection at above and below ground level. PENETRON is applied by brush or spray to either the positive or the negative side of the concrete and in the presence of moisture penetrates deeply into the structure. The ensuing chemical reaction fills microcracks, pores and capillaries with an insoluble crystalline formation, which prevents water and water-borne chemicals from entering, even under high hydrostatic pressure. Cracks that develop during the lifetime of the concrete are resealed by PENETRON, resulting in permanent concrete protection.|
|Peneplug||A rapid-setting, crystalline-based, cementitious compound designed to stopping active leaks even under high hydrostatic pressure. PENEPLUG is recommended as a waterproof plugging mortar or where rapid-setting is required.|
|Penecrete Mortar||Used in combination with PENETRON for filling non-moving cracks and construction joints, form-tie holes, honey-combed areas and structurally damaged concrete. PENECRETE MORTAR consists of Portland cement, very fine treated silica sand and various active, proprietary chemicals. It is applied in laminated layers to areas that have been opened and cut-back to sound concrete for repair to provide protection against water ingress|
