The importance of construction practice in reinforced soil structures

There is a lot of benefit to a contractor to win a reinforced soil project. However, we must realise that there is a high level of skill required. They will need to be familiar with the required design outcomes, and understand the importance of the compaction levels, required fill types, drainage detailing and facing construction to name a few.

Geosynthetic material testing – Introducing GeoCert Laboratory

The introduction of an IANZ certified geotextile testing facility in New Zealand is a big step up for the industry. For many years the closest approved laboratories were in Australia requiring samples to be shipped internationally if any site samples required testing.

Smarter Road Network Maintenance

Once again, we find ourselves deep in the middle of winter with the weather pounding our road networks and coastal areas, and many parts of the country experiencing saturated ground conditions.

Cirtex Geotextile Coastline

Geotextile protecting our coastlines

New Zealand has a very long coastline in proportion to its land mass, with approximately 15,000 kilometres of coastline, which is the 9th longest of any country in the world. This makes the country especially susceptible to the effects of coastal erosion, with frequent storm events causing major land loss and affecting state highways and private property.

Erosion & Sediment Control Guide

Erosion and sediment control are two distinct though related processes. Erosion control is preventing the washing away of soil particles by the action of wind or rain, while sediment control relates to controlling or containing the sediment laden water once erosion has taken place.

Slips on roads

Storm damage to roads: why do slips happen when it rains?

Road closures and delays on our state highways and regional roads following storm events seem to be more common than ever. Some of the big events hit the headlines and cause major delays over days or even weeks, while dozens of smaller slips go unnoticed by the media but still cause untold headaches and delays to road users nationwide.

Geogrid vs steel

Extensible vs non-extensible? or Geogrid vs Steel?

What is extensible reinforcement in a bridge abutment or MSE Wall? It sounds like we are trying to build with some stretchy rubbery product. However Inextensible reinforcement sounds more like it. Nice and strong, and it won’t stretch. Now is that the case?
