CHAIRMAN'S MESSAGE
a strong foundation is the key.”
When I founded Conseal in 1982, I had one belief: foundations are not where you cut corners. The whole building stands on that decision. Forty-four years and 800 projects later, that belief still runs the firm.
Today, we lead Conseal forward as a team of directors and senior leaders — holding the standard our clients have trusted since the Petronas Twin Towers in 1994, and continuing to specialise in the work where the ground has to be right the first time.
Our clients trust us with their most demanding foundations. We do not take that trust lightly.

OUR STORY
For over four decades, Conseal Sdn Bhd has delivered the foundation work behind Malaysia’s most ambitious projects.
Conseal does ground engineering. Not piling for piling’s sake, but the work where the ground has to be right the first time — restricted access foundations, slope stabilisation under live infrastructure, underpinning beneath occupied buildings, remedial scopes that other contractors decline to bid.
Anthony Sow founded the firm in 1982 in Petaling Jaya on a single working principle: deliver the work to a standard that earns the next call. Twelve years later, that principle put Conseal on the ground anchor scope of the Petronas Twin Towers. In the four decades since, it has shaped every hire, every rig purchase, every refused job.
As Malaysia built its rail networks, elevated highways, landmark towers, and critical infrastructure — from Klang Valley to Johor, from the coast to the highlands — we were the team beneath the surface making it possible. Today our portfolio spans bridges, LRT and MRT lines, BRT systems, KTM extensions, power transmission infrastructure, commercial towers, data centres, and resort developments.
Conseal is registered CIDB G7 across building, civil engineering, and mechanical & electrical categories — the highest contractor grade in Malaysia. The firm operates 50 specialist drilling rigs, 346 machinery units in total, and 35 company vehicles. All owned. No outsourced critical path. The work is delivered by Conseal-trained crews, supervised by named specialists, signed off by directors who answer the phone.
We’ve been trusted by Econpile Holdings, Sunway Construction, YTL Corporation, WCT Holdings, and Titijaya Land, among others — partners who return because they know what we deliver. Today, Conseal is a system-led specialist firm with 800+ delivered projects, 250+ clients, and a repeat engagement rate above 90 percent.
Our Vision
To be the geotechnical partner that Malaysia's builders return to across every phase of their most demanding projects.
Not the largest. Not the cheapest. The geotechnical partner clients return to — on the work where the ground has to be right the first time.
Our Mission
Hold the standard. Specialise the work. Honour the trust.
Deliver geotechnical work to a standard that earns repeat business. Specialise where mass piling cannot reach. Stand behind every project, named and accountable.
