If you’re looking to save on the cost of your structure – you can reduce the cost of labor by using pre-fabricated (pre-fab) walls that is still concrete based but light weight, thermally efficient, fire resistant, and acoustically effective.
Pre-fab / pre-cast walls have recently gained popularity due to its ease of use (installation), and labor cost efficiency.
The city of Cebu’s COVID shelter – a fast response make shift hospital is using this pre-fab type of wall thru pre-fab walls.
So instead of piling, hollow blocks, filling it with cement, then plastering it with concrete paste, you simply have to install these wide cut prefab walls – thus cutting your labor cost and speeding up your construction time up to 5-10 times faster.
Despite it being relatively more costly compared to hollow blocks you will be able to save a lot on your labor cost since you no longer need to apply plaster on the walls – rather just paint right away. You only need to patch the corners then apply the finishing paint directly.
These pre-cast walls are made of concrete, fibers, ash and / or coal powder, and expanded Polystyrene (EPS) foam granules – sandwiched by waterproof and flexible smoothened fiber cement board on both surfaces.
The pre-fab wall passes all required engineering and building code standards please see table as follows:

Also, because the thickest wall is only 12 centimeters, and since you no longer need to apply finishing plaster, compared to hollow blocks that could go as thick as 6 inches including the finishing plaster, this pre-fab composite wall can give you up to 4.2% living space compared to traditional hollow blocks.
Composite pre-fab wall is now our preferred walling system:
- EASY TO INSTALL – The tongue and groove design reduces installation time and decreases labor costs. The Electrical, plumbing installations, and other finishing touches can be done 5 – 10 times faster than when done on the traditional hollow blocks wall.
- FIRE RETARDANT – Tested to withstand up to 1,000˚C for 120 minutes and is compliant to the standard for Grade A Fireproof Material.
- REDUCES NOISE: – The Expanded Polystyrene (EPS) foam granules is widely known in the construction industry as good noise reducer.
- SEISMIC RESILIENT. EPS – the foam granules is highly flexible. Combined with fiber cement makes for a highly flexible yet sturdy wall that resists bending due to seismic activity.
- STRUCTURALLY AND ECONOMICAL EFFICIENT. The composite wall is made up of light materials and are 1/6th the weight of normal 120mm thick brick walls yet 60% lighter than traditional hollow blocks. This makes for a light weight wall that reduces beam and slab load which means significant cost reduction on the structural frame. The pre-cast panels are also moisture proof, water resistant, yet ready for painting right after installation (Must use recommended sealants and adhesives).
- THERMALLY EFFICIENT AND ENVIRONMENT FRIENDLY. As per tests, the composite pre-cast wall is thermally efficient in heat absorption and dissipation due to the high density of EPS and the rest of the high-density composite materials used. The EPS foam granules is the same material used in cooler chests / portable ice chests. This results in a cooler room which means you don’t need to use air conditioning as much as you do – thus saving the environment and your pocket.
Our precast walls come in 8 x 2 feet sizes in 7.5, 9.0, and 12 centimeter thickness.

Good afternoon! I am planning to build a small house 6 x 8 m. May I know how much it cost if I will your pre-cast and prefab walls? 2 rooms; 3 x 3 m and a Comfort room.
Thank you.

Hi Cip,
Is that a bungalow? 2 level house?
You can email us a rough layout of your planned house at topcebucontractors1-at-gmail-dot-com or at finefinishcebu-at-gmail-dot-com
If bungalow at 6x8m, with pre fab walls, cost will be php1.32m in todays costing.

Hi may I know if can deliver to Bacolod City should i pursue a prefabricated building construction on my property. Thanks
Author
Yes we can deliver to Bacolod – shipping fees apply.
How many panels do you need and what thickness? We have 90mm and 100mm thick panels.

Hi Krishna,
What we have is similar to Rhino but already pre filled with concrete and styro mix… All you need to do is install…
What thickness do you prefer?

A pleasant day!
We are in need of non load bearing precast block.
May I know more about your products?
Thank you very much.

Greetings. We are looking at alternatives to using the usual reinforced concrete post and CHB walls for the perimeter wall of our property in Talisay, Cebu province. This will involve surrounding the property with walls on 3 sides (and an access gate) with a fence facing the sea. Btw, the property faces the sea.
Can your group design and construct the prperty perimeter walls?

I am currently acquiring an area of agricultural land in Sogod, near Cebu, I would like the perimeter fenced with precast concrete posts and panels and incorporating two sets of gates. Is this a design/supply/installation project your company can quote for ?
Author
Hi Nick,
Yes we can design supply and install precast posts and panels for your Sogod Cebu Fence…
Please email us details on how to locate your lot in Sogod so we can make preliminary cost assessments on the design, logistics, and installation – email us at finefinishcebu@gmail.com or text us at 09214275469.

Hi would like to inquire if you have pre cast panels for fencing and how much? We don’t have blue prints yet but would like to inquire ahead it’s for a farm land.
Author
Hi Suzy,
We don’t supply panels only.
We only provide panels as part of the package which includes the design and construction.
We can start working on your blueprints – simply send us a scan/photo of your lot sketch plan or that part of the title which shows the lot’s technical descriptions.

I am interested with this item. How could i inquire?
Author
if you could email us your blueprints we can estimate the number of pre cast needed to build it.
IF you don’t have blueprints, we can make affordable one for you.
We don’t sell the pre cast, we only promote it as an alternative material

Hi….this is interesting. May I ask if you’ve all heard of eco bricks?
I actually found your website via Green ANTZ builders. They’ve been pioneers of this in the Philippines. I’m curious why aren’t more builders using this.

The usual reasons for something revolutionary to be unpopular is still the usual – cost, availability, and usability. Cost – Traditional hollow blocks cost around 12-16 pesos so new materials have to be able to compete with this kind of pricing – certainly eventually as it slowly becomes popular – it should be able to compete with the pricing. Availability – It has to be widely available and accessible – which means every builder should be able to obtain and order it without having to pay high costs on transportation and delivery, and it should also be readily available which means you should be able to receive these materials in 1-7 days maximum, otherwise it could cause significant delays in the construction. Usability – It should be easy to use for the workers and should not cause significant delays in their work. Concrete is still the popular housing material – this means any revolutionary product should be able to fully and easily substitute the traditional without incurring additional costs in materials or labor costs during construction…
