Essential Solutions for Industry Pro's
In the fast-paced world of construction, having the right materials and tools can make all the difference. Our essential selection includes a liquid waterproofing membrane, an innovative LED strip site worklights, and a concrete colour stain. Let’s dive into three of our bestselling products.
Liquid Waterproofing Membrane
Waterproofing is a critical aspect of construction, protecting structures from water damage and ensuring the longevity of your project. Liquid waterproofing membranes offer a flexible, seamless, and durable solution compared to traditional sheet membranes. Here’s why the SEMCO Works Liquid Membrane™ is a must-have:
- Ease of Application: Unlike pre-formed waterproofing sheets, our liquid membrane can be brushed, sprayed, or rolled onto surfaces, covering complex shapes and hard-to-reach areas with ease.
- Seamless Coverage: The absence of seams eliminates potential weak points where water could penetrate, offering superior protection.
- Versatility: Our formula has excellent adhesion on 15+ substrates, including concrete, metal, and wood — widely used in roofing, basements, balconies, and bathrooms.
- Durability & Flexibility: Most membranes resist cracking and can accommodate structural movements without compromising waterproofing integrity — but ours has an unmatched 1300% elongation, meaning it stretches 13 times its original size without breaking.
- Anti-Fracture Protection: SEMCO engineers managed to create a formula that combines waterproofing and crack reduction technology — so Liquid Membrane™ also helps prevent crack transmission to new surfaces.
By using our high-quality liquid waterproofing membrane, surfacing professionals can ensure superior moisture protection and prolong the life of buildings.

LED Strip Site Worklight
Adequate lighting will maintain productivity and ensure worker safety, especially in low-light conditions. Our LED strip worklight is an innovative solution offering multiple advantages:
- Energy Efficiency: LED technology consumes significantly less power compared to traditional halogen or incandescent lights, reducing energy costs.
- Bright & Even Illumination: LED strips provide consistent lighting, eliminating shadows and improving visibility in work areas, tunnels, and scaffolding setups.
- Flexibility & Portability: Unlike bulky floodlights, our LED strip is wound on a compact drum, and can be easily hung, mounted, wrapped, or positioned along surfaces — ideal for quick setup or temporary workspaces.
- Durability: Designed for rugged environments, our LED strip worklight is resistant to impact, dust, and moisture, ensuring long-lasting performance in harsh construction conditions.
- Safety Enhancement: Proper illumination minimises the risk of accidents, improving overall site safety and compliance with regulations.
Whether for night shifts, early mornings, underground areas, confined spaces, or general site work, the Site Light provides a reliable and cost-effective lighting solution for indoor construction.

Concrete Colour Stain
Do you want to freshen up your concrete colour? PreStain is our translucent water-based concrete staining system, designed to change your concrete’s colour without hiding its natural texture like a paint would. Key benefits of PreStain include:
- Translucent Colour Finish: Unlike traditional paints, PreStain etches onto the surface of the concrete, meaning any trowel marks, natural variations, and movement of the concrete will remain visible. This ensures a rich, natural aesthetic rather than a solid, uniform coating.
- Customisable Finish: Apply as a single colour or layer multiple shades for a unique look.
- Long-Lasting Durability: Proven to withstand various climates, conditions, and traffic including UV.
- Restoration & Strengthening: Enhances colour while also solidifying crumbling surfaces, making it ideal for both old and new slabs.
- Versatile Application: Suitable for both interior and exterior use, vertical or horizontal concrete surfaces.
Unlike competitors, SEMCO’s PreStain concrete colour stain is engineered for durability, ensuring your concrete remains vibrant and strong for years to come.
