That means for us to stay at the forefront of all our concrete crack repair and polyurethane crack injections across Sydney and NSW, we need to understand each climate and what might cause its peak season.
There are two effective methods of Concrete Crack Repairs which we use in repairing cracks in concrete structures, Polyurethane Injection and Concrete Epoxy Injection
POLYURETHANE CONCRETE CRACK REPAIR (Polyurethane Crack Injection)
Polyurethane crack injection is the most effective ‘Leaking Crack Repair’ method in concrete. The use of polyurethane — sometimes referred to as urethane or grout – The concrete crack injection is very popular due to its versatility of low viscosity polyurethane injection resins for leak sealing making it the most effective leaking crack repair solution. Polyurethane crack injection is used in civil, commercial and residential applications. CPR Services are frequently engaged by a wide spectrum of clients to carry out Concrete Crack Repairs throughout Sydney and regional NSW and on all types of properties and structures. We are well equipped to handle Leaking Crack Injection regardless of the size of the project.
Polyurethane Injection Concrete Crack Repair for Water Ingress.
Water ingress is when water leaks into a building or a structure through floor and wall cracks. This is often a serious defect as it can lead to weakening concrete structures creating more serious problems, both, immediate and in the future. If your building or structure is affected by such leaks, we recommend that you contact us to discuss the repair by way of Polyurethane Injection. Some of the concrete repairs and protective processes Polyurethane Injection is best suited to address and remedy include:
- Sydney Basement Wall Crack Repairs

- Floor and Wall Crack Repairs in Sydney
- Waterproofing Including Water Proofing Sydney Car Parks
- Leaking Balcony Repairs Sydney
- Leaking Cracks commonly noticed in Sydney Basement and Underground Parking Spaces in Civil and Commercial Building;
- All other cracks through which water may be leaking in Sydney
Polyurethane Injection / Concrete Leaking Crack Injection in Civil Constructions.
Polyurethane Injection is the most widely used method in concrete crack repairs due to its flexibility in application and its reliability in repairing cracks and damage in concrete structures. In addition to its efficiency as a reliable concrete crack repair solution, Polyurethane P Polyurethane Injection is also a cost-effective method in repairing leaking cracks in major concrete assets.

Epoxy Crack Injection Process
Epoxy Crack Injection is typically used on horizontal, vertical, and overhead cracks where conventional repair methods cannot penetrate or are too cost-prohibitive. As a first step in the Crack Repair process, the cause of the crack must be examined and determined. Depending on the level of crack damage, other crack methods may be used. For example, if the crack does not compromise the structural integrity of the structure, injection with polyurethane grouts or other non-structural materials may be a more suitable choice to fill the crack (ie Leaking, flexing etc). Before implementing the crack repair, the conditions that caused the crack must first be corrected. In some cases, structural cracks may be too damp and cannot be dried out, in such cases, a moisture tolerant resin is often used. Alternatively, if the crack is non-structural a low viscosity polyurethane hydrophilic resin would achieve the best result.
Epoxies for crack injection are available in a range of viscosities, from ultra-thin to paste-like are used to accommodate cracks of different widths. The main advantage of epoxies over other repair products is their high compressive strength. That’s why epoxies are the only choice for cracks requiring structural repair.
