Lintel Replacement

The most common need for lintel replacement is from corrosion, which results in lifting and cracking of masonry or concrete around the embedded steel lintel. We can replace your corroded lintels for new Galvanised or Stainless Steel.

Screw Piles and Underpinning

​We commonly use a 60mm diameter shaft screw pile but they also come in 76mm and 89mm for the purposes of restricted access situations.

There can be different size and configuration of helices on the lead sections and with our calibrated dial gauge, working with different ground conditions and a required load capacity is made easy. With our portable handheld screw pile equipment we are able to gain access through as little space as a door way if required.

Concrete Repairs

There are many causes of concrete cancer such as lack of coverage around the reinforcing steel. Magnesite topping exposed to moisture. Poorly designed waterproofing details. As the embedded steel corrodes it expands in volume and causes spalling of the surrounding concrete, often referred to as concrete cancer. Effective concrete repairs will extend the life span of the damaged structure.

Cavity Wall Ties Replacement

Due the marine environment of Sydney, wall tie corrosion has become a common issue of ties installed during construction. The ties Helicrete use are manufactured using high quality marine grade 316 stainless steel material, which won't corrode.

Wall Restraint

The need for restraining bowed and leaning walls is quite a common one. This can be due to several different reasons and one of the more common ones being the lack of lateral restraint when the building was first built, or a change in the site conditions such as close excavation or demolition works.

The jaws on the Postmaster are hydraulically operated and can accept different size posts. If you have more than one machine that you want to use the Postmaster with, it is simple to interchange the Postmaster between machines by the use of a different mounting bracket/hitch for greater flexibility than others on the market.

  • Cost savings from quicker set up - start installing posts sooner
  • Faster install times
  • Lower Maintenance costs of plant
  • Fuel savings from utilising small plant vs tractors etc
  • Transportation costs reduced from using smaller plant, eliminates flat bed truck charges to site each way
