What is hydrophilic Grout?
Hydrophilic grouts are ideal for areas that are constantly wet, because they bond better to wet concrete. They are water loving grouts which means they thrive in moist environments.
What is injection grouting?
Join now! Injection grouting is a process of filling the cracks, open joints, voids, or honeycombs, in concrete or masonry structural members, under pressure with a material that cures in place to produce the desired results like strengthening a structure and prevent water movement.
Are polymer injection grouts suitable for repair works?
The polymer injection grouts are can have be made suitable for repair works by adding modifiers to basic resins and curing agents to achieve the desired properties. These vary from manufacturer to manufacturer, and therefore should always be used based on manufacturer's recommendations.
What is sulfo-alum injection Grout?
Sulfo-alum injection grout is also based on the principle shrinkage compensation. In these grouts either shrinkage-compensating cement or anhydrous sulfo-aluminate expansive additive is used with Portland cement. The additive results, in expansion at hydration.
What is hydrophilic grout?
Hydrophilic chemical grout likes water and is able to bond to wet surfaces tenaciously; water-scavenging agents that seek out water as they react and allow the resin to work its way into water filled pores that exist in wet concrete surfaces.31-Mar-2008
Can you inject grout?
Grout injection, otherwise referred to as injection grouting, is an effective method for repairing or strengthening masonry walls. This technique involves low-pressure injection of fine hydraulic lime grout into cracks, voids, and cavities within the masonry.
What is chemical grout injection?
Chemical grouting is a soil stabilization technique that utilizes a polyurethane chemical grout injection process to transform low-fine granular soils into sandstone monolithic masses.
What is polyurethane grout injection?
Polyurethane grouting involves the injection of expanding polyurethane to fill and seal cracks and voids and relevel slabs.
How is injection grouting done?
Injection grouting is the method of filling the cracks, open joints, voids, or honeycombs, in concrete or masonry structural members. This is done under pressure with a grout material that cures in place to produce the desired results like strengthening a structure and preventing water ingress.07-May-2021

Access if required.
Where is chemical grout mostly used?
A common application of chemical grouting is to provide both excavation support and underpinning of existing structures adjacent to an excavation.
What is epoxy grout?
Epoxy grout is a unique and popular grout for tiling that does not use Portland cement or water in the mixing process. It features a hardener, pigments, epoxy resin, and silica fillers. Epoxy grout is less porous compared to the cementitious grout.17-Aug-2019
How many types of grout are there?
There are three main types of grout: cementitious grouts composed of a Portland cement base; epoxy grouts, and furan grouts, with variations available in each type.16-Dec-2018
What is polyurethane injection?
Urethane injection, also known as polyurethane or grout, is the most common way to seal and fill a crack in concrete and foundations. The popularity of urethane injection as a solution is due to its flexibility and versatility for a variety of applications.
Is polyurethane grout waterproof?
injection with a polyurethane grout 'Polyurethane grouts are designed to react with water and expand in-place, forming a tight, impermeable, elastomeric seal that immediately stops the flow of water.10-May-2016
Is Fusion Pro a urethane grout?
Is it a urethane grout or a premix? Answer: Fusion Pro is an advanced, proprietary acrylic plus silicone resin that cures as hard as cement grout. With Fusion Pro, CUSTOM created the original Single Component® Grout. ... It is not a urethane and its performance is far superior to typical pre-mix grouts.
Grouting Material Preparation
Grouting Procedures
- 1. Drill Ports
Drill short holes, which is also known as ports, into the cracks/ openings in order to be used as entry and venting terminals. Minimum diameter and depth of ports are 2.5cm and 5cm, respectively. Spacing between holes is 150 mm c/c for finer cracks to 300 mm c/c for others. Th… - 2. Seal Cracks Between Ports
The crack /opening surfaces between ports are sealed by applying epoxy, polyester, strippable plastic surface sealer for low injection pressures, or cementitious seals if surface appearance is important to the surface of the crack. Time required for hardening of seal depends upon the typ…
Injection Grouting of Massive Structures
- For massive structures, the procedure consists of drilling a series of holes, 20 to 100-mm diameter, at a spacing of 1.5 m along the crack. In a recently developed method, a bag is wrapped all along the member and the liquid adhesive is introduced at the bottom and is sucked by a vacuum pump at the top, or epoxy is injected in the cracks from one s...
