Basement Construction London

A basement or cellar is one or more floors below the ground floor of a building. It is typically used as a storage room for a house where objects such as the generator, water heater, breaker panel and fuse box, car park or air conditioning unit are located; as well as facilities such as the electrical distribution system or control point for cable television.


Building a concrete basement into your brand new house and finishing a current basement is one of the best investments you can make. Basements offer affordable rooms for a variety of purposes, from a family room to an office or extra bedroom. The most common building material is Concrete.Due to its tolerance to humidity and many design options, it also becomes the preferred option for finished flooring in basements


Type Of Basement Constructions In London

Masonry Wall Basement Construction London

The walls of the basement are made of masonry block units There are many joints where the masonry units attach to each other to ensure that your basement is fully sealed and that the walls are waterproofed (not waterproofed) to prevent water flow. The walls are made from cinder blocks and can be designed to build a poured concrete wall in a fraction of the time. The strength of these walls is achieved by reinforcing using steel rebar.

Precast Panel Basement Construction London

Poured concrete boards were raised in place with a crane. Builders of many newer residential buildings will turn to precast concrete foundation walls to save money and time on a construction site. These walls are installed elsewhere and then delivered to the building site when they are ready to be deployed. Reinforced concrete panel walls are surprisingly strong, but they are not as typical as concrete walls. Precast panels use a high-strength, low-water concrete mix, which in the long run makes them water-resistant. Nevertheless, when water damage happens, the connection between the walls and the floor usually appears.

Poured Concrete Wall Basement Construction London

The most common type of building is likely the poured concrete basement. This choice is desirable to people because it is durable and simple. As the name suggests, concrete poured basement construction starts with the poured floor foundation. Forms are used to keep the wall in place as they cool. It shows in the basement’s solid walls that do not normally cause other issues. If water leaks arise, they usually develop along the joints between the walls and the ground of poured concrete walls. Cracks can also form in the walls, which can allow small amounts of water to flow over time into the basement.

Clay or Stone Tile Walls: 

When you buy an old or traditional house, you will note that the floor of the basement has been constructed with stone and clay tile walls. In recent decades, such walls were quite common and were generally selected when other materials were not readily available. They may be very powerful, but they are also more simple as well.The greatest potential threat with the foundations of stone and clay tile is that groundwater can potentially stream through and into the basement. This is particularly true when it comes to stone walls with lots of holes and cracks. In order to address this problem, an internal perimeter drain system is usually required.
