What are floor piers and what causes them to sink?

Sometimes referred to as brick piers, or stumps, floor piers sit under timber floors to carry the floor’s weight. This weight includes the bearers, joists, floorboards, internal walls as well as the people and furniture inside a home.

There are a variety of ways to identify if you have sinking floor piers and hence, sinking floors.

The first way is to feel it. When you walk along your floors you may feel a dip when you walk or the floorboards might feel bouncy. When you open or try to close your doors, they may jam against the floor as well.

The second way is to see it. Gyprock walls may have cracked. Small objects such as toys or balls move when you place them down. Gaps may also have appeared under your skirting boards or cracks may have appeared in cornices. Cornices may even fall from the ceiling.

Why are my floor piers sinking?

More often than not, floor piers sink because of unstable ground.

Instability can be caused by a variety of factors. Leaking pipes in your home or poor nearby storm water drainage may have caused soils to erode, aerate and weaken.

Vibrations from nearby construction sites, main roads, railway lines or even airports can cause the ground to quake and destabilise.

Even thirsty tree roots can drink up all the liquid under and around your floor piers to dry the soil up and cause the ground to shift.

What floor pier repair solutions are available on the market?

Lifting floors and packing with wedges

Lifting floors and packing with wedges

This is where floors are raised using hydraulic jacks. Wedges are then fitted between piers and bearers to close the gap and keep the floors level. Lifting and packing floors is a quick-fix solution that should only be used as a short-term solution. In most cases where this method is used the floor piers continue to subside.

Steel or concrete floor pier replacement

Steel or concrete floor pier replacement

This is a method also known as ‘house restumping’. It is where floors are propped and steel or concrete piers are used to replace old brick piers. Floorboards, damaged joists, and bearers might need to be cleared and a lot of excavating needs to take place too. The downside is it can take weeks to complete and most of the time inhabitants need to move out.

Knocking floor piers down and rebuilding them

Knocking floor piers down and rebuilding them

Similar to the house restumping method, the floor needs to be propped in the area where the piers are subsiding most. The brick piers then need to be removed so a new pier footing can be excavated and filled with concrete. After the concrete dries up, new piers need to be built to the height of the bearer to stabilise the floor.
