Structural Grouting
Gumthorn delivers expert structural grouting services throughout the UK, catering to a broad spectrum of infrastructure and building projects. We specialise in grouting applications for bridges, tunnels and culverts, subways, manholes and inspection chambers, void filling beneath floor slabs, foundation strengthening and underpinning, road sub-base stabilisation, installation or replacement of bearing pads under heavy industrial machinery, sealing of redundant service pipes, ducts, and internal cavities in buildings and structures.
Our comprehensive grouting capabilities cover all major material types and injection methods, selected based on the specific structural needs, environmental conditions, load requirements, and performance criteria:
Cementitious Grouting
Traditional, high-strength, non-shrink formulations ideal for large-volume void filling, foundation stabilisation, and applications requiring excellent compressive strength and compatibility with concrete substrates.
Polymer-Modified Grouting
Enhanced cement-based systems incorporating polymers to improve flowability, reduce shrinkage, boost adhesion, and increase flexibility or durability in demanding conditions.
Structural Polyurethane Grouting
Fast-reacting, expanding resins (often hydrophobic or hydrophilic) that excel in void filling, soil stabilisation, lifting sunken slabs, sealing active leaks, and providing flexible, watertight solutions in dynamic or wet environments.
Structural Epoxy Grouting
Rigid, high-bond-strength systems offering superior mechanical properties, chemical resistance, and load transfer for precision applications such as machinery baseplates, crack bonding, and high-performance structural repairs.
