The Science Behind +Willa’s Sky Garden: How We Make Your Terrace Garden Safe, Durable & Ready from Day 1

A private garden is one of the most cherished dreams of every villa buyer. A space to grow vegetables, sip coffee, read a book, or simply watch the sunrise. But the reality is that buying extra land for a garden is expensive – and in most villa communities, it isn’t even an option.

At +Willa, we took a different path.

Instead of searching for more land, we looked upward – to the terrace. One of the biggest, most underutilized spaces in any villa.

But creating a terrace garden isn’t easy. Not if you want it to last.

Most buyers hesitate because a terrace garden comes with genuine challenges:

Leakage due to poor waterproofing

Drainage failures and water stagnation

Cracks from thermal expansion

Soil erosion due to rain

No irrigation lines or lighting points

No seating or usable layout

This is why most terraces stay empty. The dream of a garden becomes a maintenance nightmare.

At +Willa, we solved this problem through engineering – not shortcut fixes.

Our Sky Garden is not an afterthought. It is an engineered system. Every villa comes with a fully prepared, waterproofed, long-lasting terrace garden base – ready from Day 1.

The Mother Slab Waterproofing Begins with a 24-Hour Pre-Ponding Test

Before any coating or garden preparation, we fill the terrace with water and let it stand for 24 hours. This helps us detect even the slightest leakage or seepage.

If dampness appears on the underside, our team carries out acrylic injection grouting – a method that seals micro-cracks from within the concrete. This ensures the slab is structurally sound and waterproof-ready.

Dual-Layer Cement Polymer Modified Coating + Glass Fibre Mesh

On the cleaned slab, we apply two layers of a specialised cement polymer coating. This creates a flexible, crack-resistant barrier.

Why it matters:

• Prevents cracks caused by weather changes
• Strengthens joints and corners
• Keeps water from penetrating concrete

We also embed Glass Fibre Mesh in critical joints to prevent future separation or cracking.

A Protective Foam Concrete Layer (Durable Screed)

Over the waterproofing, we lay a foam concrete screed.This layer:

• Shields the waterproofing from damage
• Provides a solid base for the future garden
• Ensures long-term thermal stability

This is a crucial step most terrace garden projects skip – but skipping it leads to future leaks.
A 72-Hour Post-Ponding Test: Triple-Checked for Perfection

After the screed sets, we repeat the testing – but this time for 72 hours. This ensures:

• No leaks
• No damp patches
• No weak spots

Until the terrace passes this test, we don’t move forward.

Quality matters.

PU Primer + Polyurethane Waterproofing: Premium, UV-Resistant & Flexible

We then apply a polyurethane (PU)-based waterproofing system. PU waterproofing is considered the gold standard because:

• It stretches and adapts with temperature
• Resists UV rays
• Provides long-lasting waterproof performance
• Is seamless and joint-less

This ensures your Sky Garden stays leak-free for years.
Engineered Slope + Drain Cells for Perfect Water Flow

Water stagnation is the biggest enemy of terrace gardens. So we engineer the terrace with:

• A scientifically designed slope
• Drain cells that create a continuous water channel
• Easy water movement to outlets
• Zero stagnation or pooling

This ensures your terrace remains dry and your waterproofing stays healthy.
Biofabric Layer to Protect Soil Nutrients

Heavy rain can wash away soil and essential nutrients. Our biofabric layer:

• Locks soil in place
• Prevents erosion
• Maintains moisture
• Keeps roots healthy

This makes your garden grow effortlessly.
Built-In Irrigation, Concealed Plumbing & Lighting

A great terrace is one you can use – not one you struggle to maintain. So we integrate:

• Irrigation lines
• Water outlets
• Lighting points
• Electrical conduits
• Concealed plumbing
• Space for comfortable seating

This means no renovation, no external contractors, no drilling or wiring after handover.
The Result? A Ready, Stress-Free Sky Garden from Day 1.

At +Willa, you’re not paying extra for this.

• You’re not spending months coordinating vendors.
• You’re not risking future leakage.
• You’re simply moving in – and enjoying the space from the very first day.

A Sky Garden that is:

Beautiful

Safe

Leak-proof

Durable

Relaxing

Low-maintenance
Why We Do This

Because villas today should do more than provide rooms.

They should provide experiences.

• Space to breathe.
• Space to grow.
• Space to live better.

At +Willa, that’s the future we’re building.
