# How do you keep cement usable on a Puntland site in the rainy season? > Stack cement bags off the floor and away from walls, rotate stock oldest first, and cover loads in transit so Gu and Deyr rain never reaches the paper. - By: Editorial Team, Somali Construction Review (https://somaliconstructionreview.com/about) - Published: 31 October 2026 - Format: Practical guide (general practice) - Publication: Somali Construction Review (https://somaliconstructionreview.com) - Subject: Materials - Place: Puntland - Tags: puntland, cement, storage, material-storage - Web version: https://somaliconstructionreview.com/blog/cement-usable-puntland-rainy-season ## Key points - Cement hardens when moisture reaches it, so the store, the pallet and the tarpaulin matter as much as the delivery date. - Keep bags on a raised dry platform, clear of walls and ground, and use the oldest bags first. - Check every bag for lumps and record batch numbers before the tarpaulin comes off the truck. Cement stays usable when it is kept dry from the moment it leaves the supplier. That means a raised store floor, a waterproof roof, bags stacked clear of walls, and stock used oldest first. In the Gu and Deyr rains, the weakest points are the truck bed, the store doorway and the bottom bag in each stack. ## What does a dry cement store look like? A dry store has a solid floor above ground level, a roof that does not leak, and stacks at least a bag's width away from any wall. Bags sit on timber pallets or a raised slab, never on bare ground. Air moves through the stack, so damp does not sit between bags. Cement is a hydraulic powder. It reacts with water vapour, not only with liquid water, so humid air alone can start the set. That is why a store that looks dry can still fail: a leaking roof corner, a wall that draws damp, or a floor that floods during rain will harden the bags nearest them first. Check the store before the season, not during it. Walk the floor after rain and look for damp patches. Run a hand along the underside of the roof sheets. Look at the bottom course of each stack. Ask the storekeeper how bags are rotated, and whether the oldest batch is at the front. Keep a simple record of delivery date and batch against each stack so rotation is a written rule, not a habit. ## How should bags be stacked and moved? Stack bags flat, not on edge, in a block low enough that the weight does not crush the bottom courses. General practice keeps stacks modest in height and never against an outside wall. Move bags by hand or barrow, not by dragging, because a torn bag leaks powder and takes in damp. Heat matters too. A store with a metal roof in direct sun can get very hot, and hot cement sets faster and may develop lumps. Ask the supplier for the storage guidance on the bag, and shade the store where possible. Use the [construction material calculator](/construction-material-calculator) to work out how many bags a pour needs, then order close to that figure. Long storage is the main enemy. If a stack will sit for weeks, cover it with a tarpaulin that does not touch the bags and leave the sides open for air. Before any bag goes into the mixer, check it. A bag with hard lumps that do not break under thumb pressure should be set aside and reported. The method is set out in [How do you check delivered cement bags for lumps in Somaliland?](/blog/check-cement-bags-lumps-somaliland). > **Warning:** Never use bags that have set hard, and never break up lumps and mix them back in. Report them to the supplier and record the batch. ## How do you protect cement in transit and on arrival? Cover the load before the truck leaves the supplier, and keep the tarpaulin tied down for the whole trip. On arrival, check the tarpaulin, the truck bed and the bags before unloading. Wet paper or a damp truck bed means moisture has already reached the cement. Record what you find: date, supplier, batch number, number of bags, and any damage. Photograph torn or damp bags before they leave the truck. Write the batch on the store record so a problem bag can be traced back. If a supplier changes source or brand, keep the new delivery in a separate stack and test a few bags before mixing them into structural work.

[How do you check delivery paperwork for materials in Puntland?](/blog/check-delivery-paperwork-materials-puntland) explains what to ask for at the gate. ## What to do next Walk your cement store this week with the storekeeper. Check the floor, the roof and the wall clearance, and move any stack sitting on bare ground onto pallets. Then write a one-page store rule: raised, dry, shaded, oldest first, lumps set aside and reported. Give a copy to whoever signs for deliveries. ## Questions ### Can cement that has gone lumpy be used? Soft lumps that break easily under finger pressure may still be usable for non-structural work, but hard lumps mean the cement has started to set. Set those bags aside, record the batch and ask the supplier. Do not use them in structural concrete. ### How long can cement stay in store in Puntland? There is no single safe period. It depends on the store, the humidity and the bag. Use stock oldest first, inspect bags before each pour, and order close to what the pour needs rather than storing large stocks through the rains. ### Who should I ask about storage rules on a site? Ask the project engineer or clerk of works what the specification requires for cement storage and inspection, and follow the storage guidance printed on the bag. Ask the supplier in writing if the bag guidance is unclear. ## Sources - [Somali Construction Review: Construction material calculator](https://somaliconstructionreview.com/construction-material-calculator) - [Somali Construction Review: Concrete calculator](https://somaliconstructionreview.com/concrete-calculator)
