Concrete Injection

At the end of June, it was discovered that groundwater was seeping up through the road surface of the Vlaketunnel (A58). This leakage in the road surface caused puddles to form on the asphalt, resulting in splashing water and creating a hazardous and unsafe situation for traffic. Therefore, a swift and professional solution was necessary.

On Saturday, May 17, 2025, SealteQ's specialists carried out specialized sealing work on the aqueduct in the N302 near Harderwijk, commissioned by Heijmans and the province of Gelderland. During these operations, a water-bearing expansion joint was successfully injected, resolving a leak of approximately 3.6 m³ of water per hour.

Recently, the specialists from SealteQ West successfully completed a crucial project: sealing a leak in the Heinenoord Tunnel. Located beneath the Oude Maas, this tunnel connects the Hoeksche Waard with the island of IJsselmonde. With the A29 running through it, it serves as an important connecting route.

A wonderful workplace for the specialists of SealteQ SLS this week. They were working on the sea dike in Farmsum in recent days.

Over the weekend of 24, 25 and 26 February, Combinatie Herepoort carried out maintenance works on the longitudinal joint of a section of the temporary ring road. As part of these works, the underlying foundation and reinforced soil structure were stabilised using injection techniques.

Amsterdam is inextricably linked to water. Consider its canals and waterways. The Amstel and the IJ rivers are its lifelines. The many bridges and quay walls connecting them link the districts and neighborhoods, giving Amsterdam its unique character. Tens of kilometers of quay walls are at the end of their lifespan and in poor condition. Urgent action is required to keep the city safe, accessible, and livable. (source: www.amsterdam.nl)

Frans Nooren Heerenveen from the SealteQ Group began work on the tunnel combination at Egelantierstraat in Leeuwarden in early May 2013.
