Concrete Base for Wooden Posts - Insulates from Moisture and Extends Service Life
Concrete base: the wooden post stops touching the ground
A wooden post or column set directly into the ground constantly absorbs moisture, rots at the base and ends up compromising the whole structure it supports. The base solves the problem at its root: it raises the wood and separates it from contact with damp soil on a solid 47.2 kg concrete piece that is unaffected by water.
✅ Main advantages
Stops rising damp: the wood rests on concrete rather than on soil, which is where rot begins.
Stable foundation: a solid 47.2 kg piece that gives the post a firm seat in soft ground.
Designed for damp areas: gardens, irrigated areas and spots exposed to water.
Zero maintenance: concrete doesn't rust, doesn't rot and needs no treatment.
Clean finish: a truncated pyramid profile that sheds water outwards instead of holding it.
🏗️ Recommended applications
Wooden pergolas and porches.
Fence posts and garden enclosures.
Carport and canopy pillars.
Supports for decks and raised structures.
Any wooden column on damp or irrigated ground.

🧰 Installation
Mark out the position of each post and check that all the bases will end up at the same level.
Excavate and compact the seat, or prepare a concrete pad if the ground is soft: 47.2 kg needs firm support.
Set the base in place, level it in both directions and check it is plumb before anything sets.
Leave the head of the base above the level of the finished ground, never flush with it or buried.
Fix the wooden post to the head of the piece with the hardware suited to your structure.
Finish the perimeter so that water runs off outwards and doesn't pool around the base.
📦 Available formats
Single unit.
Pallet of 6 units (299 kg).
💡 Professional tip: the base only works if the head sits above the finished ground. The most common mistake is burying it while leveling the garden or leaving it flush with the gravel: the water then pools against the wood and you're back to exactly the problem you wanted to avoid, only now with 47.2 kg on top of it. Always leave a few centimeters of clearance and give the surroundings a slight slope. And level with the piece already in place, not afterwards: moving a base that has already been set is a two-person job.
Frequently asked questions
What is the concrete base for?
It raises the wooden post or column and separates it from contact with damp soil, resting it on a solid concrete piece. This prevents moisture from rotting the base of the wood.
What are its dimensions and weight?
It measures 31 x 31 cm at the base, 25 cm in height and 12.5 cm at the head, and weighs 47.2 kg per unit. It is made of solid precast concrete, white in color, for outdoor use.
How many units come on each pallet?
The pallet holds 6 units and weighs 299 kg. Single units are also sold.
Where can it be used?
It is suitable for wooden pergolas and porches, fence posts, carport and canopy pillars, deck supports and any wooden column on damp or irrigated ground.
How is it installed correctly?
The head of the base must sit above the finished ground, never flush with it or buried, with a slight slope around it so that water runs off outwards.
Frequently Asked Questions
¿Para qué sirve exactamente?
Para apoyar encima una columna o un pilar de madera y separarlo del suelo, de modo que no absorba humedad por la base.
¿Puede ir enterrada o enrasada con el terreno?
No. La cabeza debe quedar por encima de la cota acabada; si se entierra o se enrasa, el agua se embalsa contra la madera y el problema vuelve.
¿Cuánto pesa?
47,2 kg por unidad, y el palet de 6 unidades pesa 299 kg.
¿Qué medidas tiene?
31 × 31 cm de base, 25 cm de altura y 12,5 cm de cabeza.
¿En qué colores se sirve?
En blanco.
¿Necesita mantenimiento?
Ninguno. El hormigón no se oxida ni se pudre a la intemperie.
¿Cómo se fija el poste?
Sobre la cabeza de la pieza, con el herraje que corresponda a tu estructura.
¿Hace falta cimentación?
En terreno firme basta con un asiento bien compactado; en terreno blando conviene un dado de hormigón que reparta la carga.
