London and Kent Construction

Under garden room / basement

• First we dug the foundations 3 meters deep by 600mm wide and poured concrete with a waterproof additive.
• We let these foundations harden for 2 days.
• Then we removed the soil from the inside of the footings to create a void for the cellar.
• We then connected the reinforced mesh for the floor to the reinforced mesh at the bottom of the foundations and poured 300mm of concrete in to the bottom of the void to create the floor.
• Once completing the floor we built a retaining wall to the basement to hold back the soil to the front.
• We installed the steelwork for the ceiling and installed block work in between the steels.
• We then concreted the roof area with a 250mm concrete fully reinforced and waterproofed.
• We tanked the walls with a sika additive to keep water from coming through the walls of the basement.
• After these works we built an extension on top.
