Weather is an element of nature that is unforgiving and harsh on concrete and construction. However, that doesn’t mean that we just have to accept a limited lifespan for our concrete structures. Thanks to joint sealing solutions, there is now an answer to getting more out of concrete.

Joint Sealing is an essential component of industrial construction. Manufactured to perform under the most demanding conditions, joint sealants can withstand many years of environmental and chemical impact in any setting.

Joints between flooring slabs are to enable expansion and also the prevention of water, waste and other materials from getting into the joint however gaps in the joints in cement or flooring may cause issues if they’re not sealed thoroughly.

What are Joint Sealants?

Grouting & Joint sealing is a process of re-sealing low-pressure pipelines, primarily against the infiltration of ground water, roots and sand. This operation takes place between manholes using innovative technology. A specially developed packer is pulled through the pipeline and used to insert cement-based grout into cracks, weak joints, gaps and cavities in or around the pipeline. Culverts and man entry pipes are sealed by using a mould to insert cement. This technique is particularly useful in preventing the settling of pipelines, sink holes and obstructions due to infiltration.

In short: The purpose of joint sealants is to create a waterproof, air-tight seal between the openings of several surfaces.

When it comes to construction, joints are typically made before and after delays in the installation of concrete or through the placement of precast units. Areas are often pre-specified to restrict the work that can be carried out at one time to a convenient size, with minimum impairment of the completed structure. They may be needed to function later as expansion or contraction joints, or they might be required to be bonded to the first to preserve total structural integrity. Construction joints may run horizontally or vertically based on the placing sequence recommended by the design of the structure.

A variety of joint sealants is used in various environments, depending on the type of seal that is needed, along with the specific application for which it will be utilised. Examples of typical applications are sealing of joints in street surfaces, airport runways and hangars, sealing of construction joints in walls and floors of industrial and commercial structures.

Also, products are used for houses, water reservoirs and sewage processing structures, sealing around general household sanitary ware and certain automotive applications.
