Your building’s envelope is its first line of defence against water, wind, and weather. Without proper waterproofing and sealant services, even the most well-constructed structure can suffer costly damage—cracks, mould, corrosion, and compromised structural integrity. At Maricho, we connect you with Zimbabwe’s most reliable waterproofing professionals who deliver turnkey construction project delivery for every commercial, residential, and industrial project.
Why Waterproofing and Sealants Are Critical for Your Building Envelope
The building envelope includes walls, roofs, foundations, windows, and all points where the interior meets the exterior. Moisture intrusion is the single largest cause of premature building failure. Left unchecked, it leads to:
- Structural decay – Steel reinforcement rusts, concrete spalls, timber rots.
- Health hazards – Damp environments breed mould, mildew, and bacteria.
- Energy loss – Wet insulation loses its thermal resistance, driving up utility bills.
- Aesthetic damage – Stains, peeling paint, and efflorescence ruin appearance.
Turnkey construction project delivery means we handle every stage—from assessment and design to application and warranty—so you don’t have to manage multiple contractors. Your building envelope stays dry, durable, and energy-efficient for decades.

The Maricho Difference – Turnkey Construction Project Delivery
Coordinating multiple trades for a building envelope project is complex. A delay in one task can cause moisture exposure and rework down the line. Turnkey construction project delivery means we manage the entire scope—from initial survey to final inspection—under a single point of accountability.
What Turnkey Delivery Includes
- Comprehensive site assessment – Identify all potential leak paths using moisture meters, thermal imaging, and pressure testing.
- Specification and material selection – Choose the right waterproofing system for your climate, structure, and budget.
- Scheduled application – Our teams work in sequence with other trades (roofing, cladding, MEP) to avoid gaps and overlaps.
- Quality assurance – Every joint, seam, and termination is inspected before the next phase begins.
- Defects liability period – We stand behind our work. If a leak appears, we fix it promptly.
You get one contract, one warranty, and one team to call. No finger-pointing between subcontractors. No hidden costs.
Our Process – From Assessment to Completion
Every waterproofing and sealant services project follows a proven workflow that minimises disruption and maximises long-term performance.
Step 1: Initial Consultation
We listen to your concerns, review drawings, and inspect the site. Our goal is to understand your building’s unique vulnerabilities and your project timeline.
Step 2: Detailed Survey & Testing
Our technicians use industry-standard diagnostic tools to pinpoint existing leaks, measure moisture content, and assess substrate condition. This data informs the specification.
Step 3: System Design & Material Selection
Based on the survey, we recommend the best waterproofing system—whether cementitious, liquid-applied membrane, bituminous, or polyurethane sealant. We consider surface type, exposure, traffic load, and budget.
Step 4: Surface Preparation
No waterproofing system performs well on a dirty or damp substrate. We clean, repair cracks, prime, and ensure the surface is ready for bond.
Step 5: Application & Curing
Our certified applicators follow manufacturer guidelines precisely. For liquid membranes, we control thickness and curing time. For sheet membranes, we lap and seal overlaps correctly.
Step 6: Inspection & Testing
After application, we flood-test flat areas, pressure-test joints, and visually inspect every detail. A comprehensive report is provided.
Step 7: Maintenance & Warranty
We offer periodic inspections and maintenance programmes to extend the life of your waterproofing. Our warranty covers materials and workmanship.
Types of Waterproofing Systems We Use
Choosing the right system is critical. Here’s a quick comparison of the most common options we install through turnkey construction project delivery.
| System Type | Best For | Key Advantages | Typical Lifespan |
|---|---|---|---|
| Cementitious Waterproofing | Basements, water tanks, swimming pools | Easy to apply, good adhesion, affordable | 5–10 years |
| Liquid-Applied Membrane | Balconies, terraces, flat roofs | Seamless, flexible, suitable for complex shapes | 10–15 years |
| Bituminous Membrane (torch-on or self-adhesive) | Below-grade walls, foundation slabs | High durability, proven track record | 15–25 years |
| Polyurethane Sealants | Expansion joints, window perimeters | Excellent elasticity, UV resistant, paintable | 10–20 years |
| EPDM / PVC Sheet Membranes | Large flat roofs, green roofs | Excellent seam strength, UV stable, long life | 20–30 years |
