In case of existing Basement where no access is available for treating the structure from outside & below, we propose to treat the U/G structure by our “Injection &Surface” Method.

The  junction of the bottom raft with the vertical wall is to be opened by us & filled with metal aggregate of nominal size along with injection (coupling). In the wall area all construction joints are opened to provide Injections: Injections shall be provided as & where found necessary are used as per site conditions. The Injections are filled with cement slurry (grouting). After the injections are finished with cement grouting. We shall provide a layer of P.S. of about 2” thick on the floor & the vertical wall is covered with our waterproof layer of 1” thick. Like this the structure is waterproofed from inside.

Note: This method is also applicable for Underground tanks. Lift Pits & Overhead water tanks.

The final surface of the floor will be finished smooth in cement colour & that of the walls with cement.

It may please be noted that our treatment should in no manner be punctured or damaged If any fixture are necessary. Then they will be provided over our treatment. so that our treatment is not damaged or tampered with.

In case the floor of the basement is to be subjected to rough and/or heavy use, then a suitable wearing coat on our surface shall be necessary to provide by the owners.

Is case any existing treatment is present. The same shall be removed by us to expose the surface of R.C.C. Raft.
