Mainmark includes a team of airport specialists who have a great deal of experience in dealing with the differing construction types found at airports. We understand how to work inside tight NOTAMs and can provide solutions to repaire the airports which incur minimal interference with traffic.
Our experienced engineers can identify and eliminate sub-surface voids. Usually caused by water, these are the #1 enemy of pavement whether hard or flexible. Mainmark has multiple solutions depending on the individual case. Many voids are injected with a fast setting structural resin which can improve SBC by 500% or more. Alternatives are our specialist Terefil foam concrete and perhaps even our Micro Pile solution.
Concrete slabs can be quickly brought back to grade when Mainmark injects a purpose built expanding structural resin under the slab to fill voids, re-support the slab, and lift it back to grade. This work is fast, depending on the problems encountered, and often 2 -3 slabs can be re-levelled in a single 4 hour NOTAM. Slower setting foam concretes are also available for this task depending on the specific problem.
Mainmark can review your water plan and inspect for water related issues. It is not unusual to find soil pipes leading under runways, or to find water travelling quite long distances though layers in the paving. We can help find the sources of these problems and resolve them before pavement breaks or delaminates.
Mainmark is adept at resolving the many issues that confront the owner of concrete pavement. These include:
Mainmark has undertaken extensive projects at Don Mueang airport and other airports where we have provided assistance include Hat Yai, Chennai, Sydney, Brisbane and Melbourne airports.
The soil under docks is often wet or compressed from heavy use. As a result, the concrete panels on the top of such soils become uneven. Uneven concrete panels get damaged very quickly necessitating early replacement. Apart from being wasteful of port infrastructure, in a busy port, the process of concrete slab replacement can hinder operations and slow productivity.
Mainmark’s method of slab re-levelling ensures that concrete slabs are re-levelled promptly and permanently. Uretek uses laser levelling to ensure that slabs are perfectly matched – and perfectly supported. Pavements are then able to deliver their full service life.
A set of four slabs usually takes less than a day to re-level. Port operations can continue around our operations team, and the work area can be used as soon as we have left.
