Basement Waterproofing For a Commercial Development in Hurlingham.



The Hurlingham location provided a difficult waterproofing challenge because there is a lot of stagnant underground water in that location. The confined space in the lift shaft also meant that only 2 people could work inside the lift shaft at any particular time. The depth of the basement also provided a challenge as the floor level of the basement was below the level of existing drains and the ground water table.

In addition to this, we discovered the floor slab was chipping off gradually due to abrasion from moving vehicles. That was a sign that the concrete floor slab surface was not hard enough to withstand abrasion and impact.

Our strategy was to waterproof the basements and lift shafts first by applying PENETRON INTEGRAL CAPILLARY SYSTEM on the concrete walls and floor slab. Spots where ground water could be seen physically flowing into the basement and lift shafts were plugged using PENEPLUG RAPID SETTING COMPOUND.

Another 100mm thick layer of concrete was cast on top of the existing floor slab. The new concrete was treated with PENETRON INTEGRAL CAPILLARY SYSTEM to make it water tight. We also treated the new concrete floor slab with PENESEAL FH CONCRETE DENSIFICATION FORMULA to improve the abrasion and impact resistance of the floor slab, or in simpler terms, to harden the concrete.



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.
Peneseal FH A clear, reactive penetrating sealer designed to permanently protect, preserve and strengthen concrete and masonry building materials, PENESEAL FH penetrates deep into concrete surfaces and reacts with the elemental concrete ingredients to solidify them into a harder, denser, stronger concrete mass. Alkali salts and minerals are flushed out in the process, eliminating efflorescence and leaching, and increasing bonding of surface coatings.
