Understanding Underpinning process

Before we proceed any further with our article in this series on laying ceramic floor tiles, it is important that we first understand what an underpinning process is. Laying ceramic tile flooring can be difficult and requires many steps. This will include the installation of the main base materials, proper adhesives, subfloor preparation and the actual tile laying.

Concrete’s underbody waterproofing is essential as it acts as a barrier between your building’s exterior and interior. In terms of concrete, this is called underbody waterproofing and is undertaken by a structural engineer trained and experienced in the application of such processes. The ceramic tile flooring project requires a detailed program of preparation, including the preparation of the foundations. Once these foundations are guaranteed to be sound and solid, the next stage of the underbody waterproofing process begins.

The application of concrete or other rigid masonry products such as bricks, tiles or stones, and the utilisation of mechanical systems such as pulleys, hydraulic jacks and inclined plane hoists, are utilised to apply the concrete or other rigid masonry to the foundation. Qualified structural engineers use the appropriate machinery and equipment to apply the masonry. Concrete or other rigid masonry can be placed directly onto the foundations without the use of beams or joists. After the concrete or other rigidly masonry has been laid on the foundations, a waterproof mix is applied to the area where the floor will be laid. This waterproof mix is typically a water-based solution, typically a polymeric water based compound, which is capable of providing both sound insulation and an anti-permeation agent.

When the concrete or other rigid masonry is exposed to the underside of the earth, or silt, it is known as being ‘on buried’ or ‘under buried’. Concrete or other rigid masonry that is under buried has a layer above it on the earth’s bottom. This silt acts as a barrier against water getting through the foundations. The application of a water-based waterproof mix directly on the silt will ensure that the ceramic tile floor project is well underpinned.

The term “overbanked” refers to concrete or other rigid masonry that is exposed to water. Once the waterproof mix has been applied over the top of the silt layer, it is then necessary to move the exposed silt to the position in which it can be consolidated, or filled in, with a trowel. This consolidated silt will then provide the firm base upon which the waterproof fabric can be laid. This is called ‘overbanking’. This method is common, but it is also possible to apply dry or wet mixes directly to the foundations or piles. With the right tools, you can create a solid foundation without the need for an underpinning process.

The injection bored process is the third and final stage in the paludarium. It involves the construction of a permeable layer (or microfilm). This application involves inserting a camera or robotic probe into the pit or pile. Images are taken of the aggregate after it has cooled and hardened. After these images have been assimilated, an accurate computer model can be created from these data and a micro-pile lining can be injected into the pit.

The above three processes are used to provide a solid and secure layer of soil around the foundations of buildings and homes. A good foundation has the capacity to resist the weight of the eventual load and the stresses that are placed on it throughout its life. By working closely with a leading micropile contractor, you can develop a bespoke solution designed to meet the exact needs of your buildings and footings. A micropile contractor can help you lay foundations by taking care of everything from the design of the pile to the laying and waterproofing of the concrete, and finally to the foundation footings.

Foundations can crack at any time – nature does not discriminate! It is not uncommon for cracks in the underlying structure to progress upwards, leading to significant structural problems. The soil’s weight pushing on floors and beams can result in significant energy being wasted. It is possible to simply excavate the ground to remove this extra load. Your micropile engineer can create a solid foundation that is structurally sound to reduce this problem and ensure safe use of your property and building.
