Although the many atttibutes of concrete such as compressive strength, excellent durability and versatility are well known, concrete floors are not completely immune from problems. This Good Repair Guide focuses on the restoration of the appearance of concrete floors.

Inconsistency of the original concrete mix, poor surface finishing and inadequate curing may result in a floor finish that is less than acceptable. Shrinkage cracking, staining, surface pitting and wear from vehicle or foot traffic can also be a problem.

Residential basements are common in houses built on sloping ground and can be valuable and useful spaces if they are dry and warm. In many cases, the use of a basement changes over time as household size, lifestyle and interests change. 

Work may be required to upgrade the space. High internal humidity, musty odours and efflorescence in below-grade basements are all signs that moisture may be entering the space through porous concrete retaining walls. 

This Good Practice Guide covers only basement walls of residential buildings on sloping sites that are no more than one storey in height below natural ground and not subject to hydrostatic pressure. Where a wall is subject to hydrostatic pressure from groundwater or a spring, seek specific design advice from a specialist damp-proofing company.

External timber steps and handrails are exposed to all weather conditions, including regular wetting and drying and high levels of UV light. Regular wetting and drying causes swelling and shrinkage of the timber, while changes in ambient temperature results in continual thermal expansion and contraction. The constant movement of the timber causes warping and cupping, joints to open up, nails to pop and fixings to become loose. In addition, timber that remains wet for extended periods of time becomes slippery, and rotting may occur.

This Good Repair Guide identifies some of the common problems and repair options for external timber steps and handrails. When damage to external steps is extensive, the best option is often full replacement.

Driveways and paths require maintenance and may need to be repaired from time to time. The frequency and type of repair depends on the surface finish. Paths and driveways can become overgrown, and tree roots growing underneath are likely to cause cracking and unevenness of the surface.

This Good Repair Guide identifies some of the common problems with driveways and paths and describes repair options. If damage is extensive, however, the best option may be removal and a full replacement of the driveway or path, which is outside the scope of this guide.

A bouncy or springy floor or a floor that is noticeably uneven is often the first indication that there may be a problem with the subfloor framing.

Subfloor timbers include joists, bearers, wall plates, jack studs, braces and stringers. They are structural components of a building, and any damaged or understrength subfloor timbers must be repaired or replaced regardless of the cause.

This Good Repair Guide looks at the causes of common problems with subfloor timber and outlines the repair options.
