Structural Grouting


Structural Grouting

Total specialist maintenance provide specialist structural grouting services to bridges, tunnels culverts, subways, manholes and chambers, under floor slabs and strengthening of foundations, roads, bearing pads under heavy machinery, filling of redundant service pipes, ducts and cavities within building structures on a national basis and for various market sectors

Total specialist maintenance carries out all forms of Grouting which include Cementitious grouting, Polymer modified grouting, Structural polyurethane grouting and Structural epoxy grouting. Total specialist maintenance are an approved installer of all of the major structural grouts material manufacturers’ product ranges, we work hand in hand with the material manufacturers to develop the most appropriate and cost-effective repair specification to ensure that the client is provided with the best solution to enhance the life the structure/asset.


Problems that lead to the requirement for structural grouting

Initial structural defects are often attributed to water ingress, failure of surface water/mains water drainage systems, the identification of voids and cavities and the requirement to enhance structures that require an increase in the load-bearing capacity

Pining and grouting

Void filling

Manhole sealing

Infilling of redundant pipes and services

Foundation strengthening

Back grouting to tunnels, bridges and subways

Grouting under machinery bearing pads

Typical compressive strength values for traditional construction grouts are 6N/mm2 to 65 N/mm2 at 28 days, however epoxy grouts can have a significantly higher early strength gain with approximate values of 40N/mm2 within 24 hours which can assist with time critical projects.

Structural grout is often used in reinforced masonry to fill voids in masonry, housing reinforcing steel within precast concrete, securing the steel in place and bonding it to the masonry, filling of redundant pipes and services, pinning and grouting, manhole sealing, foundation strengthening, back grouting to tunnels, bridges and subways, grouting under machinery bearing pads, grouting under bearing pads on bridges and steel work

Grouting is also done for providing additional strength to the foundation of load-bearing structures. Grouts are used for different applications like repairing of cracks, filling voids, sealing joints for waterproofing of the submerged structure like tunnels, canals, load bearing enhancement and for ground stabilisation.

Grout is a composite material generally consisting of water, cement, sand, Epoxies and polyurethanes. It is typically used for filling voids under machines or other structural elements, sealing joints and openings in surfaces and reinforcing existing structures.

Concrete grout is used in most column base connections to facilitate the construction process and to ensure that full contact is achieved between the steel plate and the concrete pedestal.

There is no standard for grout thicknesses, however this is dependent on the product selection and if the grout contains aggregate or not.

“Non-shrink” grouts are commonly used for a range of concrete repair applications including patching of honeycombs, tie-bolt holes, accidental damage, breakouts, and pack-filling of gaps and voids. Non-shrink grouts are selected because they are seen as good quality, high-strength mortars.

Water evaporates faster with high temperatures, low humidity, solar heating and high winds which causes the cementitious material to lose water early (before final set) leading to plastic cracking, which is evident by the appearance of these fine cracks within hours of application out to 72 hours.

Grout takes between 24 and 72 hours to dry on average. However, the exact drying time depends on the type of grout, humidity levels, and whether you’re working indoors or outside. Most manufacturers advise waiting three to seven days before exposing grout to moisture.
