Soil injection is used in many construction projects to provide an underground construction layer. This horizontal soil sealing is an alternative to underwater concrete or a combination of sheet piling and pumping.
Soil injections are used to prevent the inflow of groundwater from below. For this purpose, a mixture of water, water glass and a hardener is injected into the soil at a predetermined depth, lower than the excavation level to prevent bursting of the construction pit floor.
After injection, this water-glass mixture forms a sphere that squeezes between the grains of sand. Because the injected spheres of fluid overlap, there is eventually no room for groundwater. This is called permeation grouting. After about seven days, the water-glasm mix has cured to the point that it has formed a water-inhibiting gel layer. This layer reverses the groundwater, creating a water-glass carpet. After this, well drilling can begin.
Grondinjectie Nederland has an automatic pumping system for performing soil injection that injects the liquid into the soil at the right place and in the right dosage. Our advanced water glass injection unit is equipped with the latest technology. As a result, the injection process is fast and efficient.
Soil injection is a technique that can be used effectively to fix leaks in sheet piling. Sheet piling is often used as a water barrier or to stabilize soil during construction projects, but over time it can develop cracks, holes or weak spots that allow water to enter the structure. This can lead to structural damage and safety hazards. Soil injection provides a solution by repairing and strengthening the subsurface around and behind the sheet piling to make it watertight again.
Soil injection has several advantages over other methods. For example, it can be applied without the need to remove the sheet piling, saving time and costs. In addition, injection can be carried out in specific areas, allowing for a targeted approach. This makes it a flexible solution that can be tailored to the nature and extent of the leakage.
Soil injection is an effective technique for eliminating leaks around tension anchors and ensuring the structural integrity of a building structure. Tensile anchors are commonly used to stabilize and anchor sheet piles or other supporting structures. They run through the ground and are placed under tension to hold the structure in place. However, when leaks occur around these anchors, it can cause the structure to weaken because water or groundwater can enter the construction area past the anchor.
Soil injection plays an important role in the repair of underwater concrete and provides an effective way to address leaks and structural problems. Underwater concrete is often used in foundations, sheet piling, locks and other structures that are in constant contact with water. Over time, wear, cracking or weakened joints can cause underwater concrete to leak, which can lead to further damage to the structure and the ingress of water into the construction area.
A major advantage of soil injection for underwater concrete is that the repair can be made without the need to lower the water level or drain the construction site. As a result, repairs can be made quickly and cost-effectively with minimal disruption to the environment. In addition, the injection materials can be adapted to the specific requirements of the structure and environment, such as the degree of water pressure and type of leakage, ensuring a durable and long-lasting solution.
Soil injection is an effective method of remedying leaks caused by seepage, also known as swelling. Swelling occurs when groundwater surfaces from below due to pressure and penetrates the bottom of construction pits, sheet piling or basements, for example. This can cause serious problems because the groundwater disturbs the stability of the soil and can lead to subsidence or even complete collapse of structures.
Soil injection has the advantage that it allows a highly targeted approach, where injection can be carried out exactly where leakage due to seepage occurs. Moreover, the process can be carried out without the need to dry out the work area or take other drastic measures. This makes it a quick, efficient and cost-effective solution. By stabilizing the water pressure in the soil, soil injection not only reduces the risk of further leaks, but also increases the safety and durability of the entire structure.
An underground, horizontal barrier that stops groundwater rising into an excavation. It offers an alternative to underwater concrete or sheet piling combined with dewatering.
A mix of water, water glass and a hardening agent is injected at a set depth below the excavation. The injected pockets of liquid overlap, leaving no gaps for groundwater to pass through.
After about seven days, the water glass mix sets into a water-resistant gel layer. Dewatering can then begin.
